Abstract

A disposable absorbent article may include a topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet, and a leg gasketing system. The leg gasketing system may include an inner cuff and an outer cuff; the inner cuff may include an inner cuff folded edge and an inner cuff material edge and the outer cuff may include an outer cuff folded edge and an outer cuff material edge such that the web of material is folded laterally inward to form the outer cuff folded edge and folded laterally outward to form the inner cuff folded edge.

First claim

What is claimed is:

1 . A disposable absorbent article for wearing about the lower torso of a wearer, the disposable absorbent article comprising: a first waist region, a second waist region, a crotch region disposed between the first and second waist regions; a first waist edge and a second waist edge; and a first longitudinal edge and a second longitudinal edge, the disposable absorbent article comprising:
1.) a topsheet; 2.) a backsheet; 3.) an absorbent core disposed between the topsheet and the backsheet; and 4.) a leg gasketing system, wherein the leg gasketing system comprises an inner cuff and an outer cuff; wherein the inner cuff comprises an inner cuff folded edge and an inner cuff material edge, and the outer cuff comprises an outer cuff folded edge and an outer cuff material edge, such that at least one web of material is folded laterally inward to form the outer cuff folded edge and folded laterally outward to form the inner cuff folded edge, wherein the leg gasketing system is joined to the topsheet and/or backsheet between the inner cuff folded edge and the outer cuff folded edge in the crotch region, and the inner cuff has an air permeability of less than 36.9 m 3 /m 2 /min and the outer cuff has an air permeability that is greater than about 5 m 3 /m 2 /min and less than 65.6 m 3 /m 2 /min.

2 . The disposable absorbent article of claim 1 , wherein the leg gasketing system does not comprise a polymeric film.

3 . The disposable absorbent article of claim 1 , wherein the leg gasketing system comprises an N-fiber material.

4 . The disposable absorbent article of claim 1 , wherein the inner cuff has a hydrostatic head of greater than about 2 mbar and the outer cuff has a hydrostatic head of less than about 200 mbar.

5 . The disposable absorbent article of claim 1 , wherein the inner cuff has a Low Surface Tension Fluid Strikethrough Time of greater than about 15 seconds and less than about 200 seconds and the outer cuff has a Low Surface Tension Fluid Strikethrough Time of greater than about 20 seconds and less than about 200 seconds.

6 . The disposable absorbent article of claim 1 , wherein the inner cuff has an opacity of from about 15% to about 50% hunter opacity and the outer cuff has an opacity of from about 45% to about 75% hunter opacity.

7 . The disposable absorbent article of claim 1 , wherein the inner leg cuff has a WVTR of less than about 5500 g/m 2 /24 hrs and the outer leg cuff has a WVTR of greater than about 4250 g/m 2 /24 hrs.

8 . The disposable absorbent article of claim 1 , wherein the leg gasketing system comprises at least two elastic members on the inner cuff.

9 . The disposable absorbent article of claim 1 , wherein the leg gasketing system comprises at least three elastic members on the outer cuff.

10 . The disposable absorbent article of claim 1 , wherein the leg gasketing system comprises four elastic members on the outer cuff.

11 . The disposable absorbent article of claim 1 , wherein the leg gasketing system is comprised of one web of material.

12 . The disposable absorbent article of claim 1 , wherein the leg gasketing system is comprised of multiple webs of material.

13 . The disposable absorbent article of claim 1 , wherein the outer cuff material edge is disposed laterally inboard the inner cuff material edge.

14 . The disposable absorbent article of claim 1 , wherein elastic members are located between the inner cuff material edge and the outer cuff folded edge.

15 . The disposable absorbent article of claim 1 , wherein elastic members are located between the inner cuff folded edge and outer cuff material edge.

16 . The disposable absorbent article of claim 1 , wherein the outer cuff folded edge is located laterally outboard of a chassis edge in the crotch region.

17 . The disposable absorbent article of claim 16 , wherein the disposable absorbent article comprises a longitudinal centerline, and the chassis edge is not parallel to the longitudinal centerline.

18 . The disposable absorbent article of claim 1 , wherein the backsheet is attached to the leg gasketing system between the outer cuff material edge and the topsheet.

19 . The disposable absorbent article of claim 1 , wherein the inner cuff is two layers.

20 . The disposable absorbent article of claim 1 , wherein the disposable absorbent article is a pull-on pant.

21 . The disposable absorbent article of claim 1 , wherein the disposable absorbent article is an incontinence brief.
